Can muscle power predict recovery after ACL surgery?
NCT ID NCT07765173
First seen Aug 14, 2026 · Last updated Aug 14, 2026
Summary
This study follows physically active people who undergo ACL reconstruction surgery to see how their knee muscle strength and power change over six months. Researchers will measure muscle function in both legs and compare it to patients' own reports of how well their knee works. The goal is to understand whether objective muscle tests align with how patients feel and function after surgery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Muscle function assessments (strength and power tests) and questionnaires
- What this could lead to
- If successful, this could improve rehabilitation strategies for ACL reconstruction patients by better linking objective muscle recovery to patient-reported outcomes.
- What could go wrong
- This is an observational study, so it cannot prove cause and effect. Results may not apply to all patients, and the correlation between strength and patient-reported function may be weak.

Inclusion Criteria: * Patients requiring isolated or complex ACL reconstruction (combined with a meniscal injury) * Patients who are physically active (Tegner score ≥ 4) and wish to resume such activity. * Patients with no history of surgery on the ipsilateral knee (i.e., native knee). * Patients able to comply with the study procedures * Patients who have given their free and informed written consent, having been informed of the purpose of the study, its procedure and its risks. * Be affiliated to a social security scheme. Exclusion Criteria: * Patient with comprehension difficulties * Recurrent rupture of the ipsilateral ACL * Multi-ligament injuries (i.e., injury to the medial collateral ligament, lateral collateral ligament or posterior cruciate ligament)
